MACHINE FOR DELINTING COTTON-SEED.

SPECIFICATION forming part of Letters Patent No. 431,665, dated July 8, 1890.

Application filed October 2, 1889. Serial No. 325,800. (No model.)

Y0 @ZZ whom it may concern:

Be it known that I, CHARLES K. MARSHALL, a citizen of the United States, residing at Vicksburg, in the county of Tarren and State of Mississippi, have invented certain new and useful Improvements in Machines for Delinting Cotton-Seed; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention consists in a novel combination of parts whereby cotton-seeds are passed from one hopper, then blown by a fan beneath a curved director into another hopper, and from said hopper are lifted by an endless carrier and delivered between scouring-surfaces of a cotton-delinting machine, the combination being suoli that the seeds arespread out in a broad thin sheet and deprived of dirt and other foreign substances between the first and second hoppers, and are thus putin a condition for being` rapidly and constantly fed by the endless carrier to a cotton-dehnting machine having a shallow yet very long feed-passage without liability of the machine clogging.

My invention also consists in the combination of an endless scouring-belt, an inclined screen, and a rotary finisher or polisher consisting of a stationary disk having scouringsurfaces and a revolving disk having a feeding-eye and dressed with brushes or other analogous scouring projections, whereby the seeds are first deprived of adhering cottonlint and then further rubbed for the purpose of removing all the fine cotton fuzz and finishing them with a clean or polished surface.

My invention also consists in certain other combinations, as will be hereinafter described and claimed.

In the accompanying drawings, Figure l is a longitudinal section of my improved feeding mechanism in connection with a scouringsection of a cotton-delinting machine, which may be similar to one of the scouring-sections shown in an application for a patent filed by me July 3, 1889, Serial No. 316,877, the said feed mechanism and scouring-section being shown in connection with rotary finishing or polishing mechanism. Fig. 2 is a plan livery-hopper.

Fig. 3 is a vertical section on an enlarged scale of the frame and of the receiving and discharging gutter of the finisher or polisher and an elevation ofthe finisher or polishing mechanism. Fig. 4. is a broken vertical section and partial elevation of the finishing or polishing machine and its frame. Fig. 5 is a detail section of part of the upper 'and lower finishing. polishing disks. Fig. 6 is a broken detail sectional view showing in part the endless carrier, comb-plate, and de- Fig. 7 is a broken plan View showing the relation of the teeth of the endless carrier to the comb-plate. Fig. S is a detail rear View of the blast-fan, showing both its tapered and iiaring form. Fig. 9 is a side elevation of my invention, illustrating a mode of driving.

A in Fig. l is designed to represent a portion of a scouring-section similar to what is shown in my aforesaid application, the same here consisting of an endless slatted belt ct, suitably dressed with rubbing and scouring means, an inclined screen h, conducting tailboard c, a revolving cylinder b, with bristles or pins in its periphery at the mouth-of the scouring mechanism, and frame f for supporting the same, said frame being inclosed by a casing f. these parts maybe constructed and operated and combined with an air-tight casing and suction-fan and trunk in substantially the manner and for the same purpose as in my aforesaid application, and therefore a further illustration and description of the same here is unnecessary, as no claim is made in this application to said scouring-section or the parts thereof separately.

B represents a chamber, closed at front, sides, back, and top, and resting upon the ground or flooring of a building.

O is a main feed-hopper on top of the chamber at the rear end thereof, and D is another hopper at the forward top end of said chamber, from which the cotton-seeds are delivered to the scouring mechanism at A by means presently described.

E is a refuse and air-escape flue leading from the hopper D. I/Vithin the hopper D a toothed elevator` in form of an endless belt F I wish it to be understood thatA IOO is applied in an inclined position upon rollers e e', so that the belt on its rear side is parallel with and touches or nearly touches the rear inclined side of the said hopper. This Velevator reaches from the bottom or angle g of the hopper to a position above its upper edge, so that the seed carried up by the teeth or hooks h on the belt F are discharged upon an inclined conducting-board m, which forms a part of the mouth of the scouring-section A, and are thereby placed in a position for being forced or urged between the parts of said mechanism by the revolving brush or pin cylinder d, as in my aforesaid application.

Behind the roller c at the'top of the belt, and also forward of the same, plates mm2 are provided, the rear one fm serving for keeping back surplus seed as thc teeth go upward, and the forward one m2, which is toothed similar' to a comb, preventing seed passing back as the teeth go downward. The plate m may be fitted as a slide and adjusted farther away from or nearer to the elevator and confined by a screw m3, and thus regulate the amount of seed supplied to the scouring-section A.

In the main hopper C a swinging valve-plate 'n is applied and made adjustable by a screw fn', so as to decrease or increase the size of the discharge-passage at the bottom or angle of said hopper,and a revolving spiked cylinder 'n2 or other equi valent agitator may be applied in the hopper for insuring a uniform discharge of the'seed.

Between the hoppers C and D the metal top vof the chamber B is curved,-as shown at B,and said curved portion rises higher than the rear side of the hopper D in order to leave a passage G for cotton-seed into said hopper beneath the curved part of the top, as shown.

H is a blast-fan arranged in the bottom of chamber B, directly under the main hopper C. The nozzle or discharge end H of the fancase ismade with a taper and flared laterally, so as to discharge the air in abroad thin sheet the full length of the hopper C and nearly the full width of the scouring-section A. The said nozzle extends up very near to the angle or bottom of the hopper, and its discharge end-is in rear of the discharge-opening of the hopper, and therefore when the blast of the fan escapes it strikes the cotton-seed falling from said opening of the hopper and carries them on a curved line corresponding to the curvature of the top B of the chamber B and forces them into the hopper D, as illustrated in the drawings, and as the seeds pass to the hopper D any sticks, stones, nails, and refuse of greater specific gravity than the seed and of a weight sufficient to overcome the force of the blast are defiected by the rear inclined side of the hopper D and deposited in the chamber B, as also illustrated in the drawings.

It will be understood that as my cotton-seeddelinting machine may be from three to four feet wide, and the spaces between the scouring-surfaces shallow, it is a desideratum to have the seed supplied regularly in thin masses. This is accomplished very satisfactorily by elevating or feedin g the seeds, which are blown in thin masses into the hopper by t-he blast-fan, by the broad-toothed elevator or feed-belt F, and from thence delivering the broad thin masses into the scouring-section A. In connection with scouring mechanism, as A, I employ a finisher or polisher, consisting of a stationary frame I, a circular guttered seed-receiver i, having' an inclined bottom t" and a discharge-chute i2, a vertical shaft J, a stationary perforated screening-disk K r, dressed on top with a suitable frictional cleaning-surface of square woven wirej, and a revolvingcircular disk L, dressed on its under side with tufts or bristles, forming a brushing and polishing disk. The brushing and polishing disk L worksin concert with the friction al screeningsurface of disk'K, and the cottonseeds, which have been almost completely deprived of lint in the section A of the machine, are finished or polished.

It would be impracticable to put cottonseeds which have not been delinted into the finisher or polisher, and it is only intended to employA the finisher or polisher as ,an adjunct of a delinting-machine, as illustrated in the drawings.

For the purpose of rendering the brushingdisk self-adjusting and varying its force a spring 7c is fitted around the upper end of the shaft J and made to rest on a collar Z of the shaft J, and'against this spring a collar 7c of an adj listing-screw M is made to bear. The screw M is fitted to a stand ard M of the frame I, and by turning it down the pressure is increased and by turning it up it is decreased. If the disks K and L should become clogged, the spring allows the upper disk to yield, and thus avoid breakage of the machinery. Said spring also insures a sufficient frictional contact of the brushes of the disk with the seeds passing between the disks. At the center of the disk L a feeding-eye P is provided, and immediately beneath this eye a series of' shallow curved guiding conducting-ribs n4, Fig. 2, vare provided upon the stationary disk K, so as to insure the iowing of the seeds beneath the disks under the action of the revolving brushing-disk. The seeds as fast as finished or polished between the disks pass out at the peripheries of the ldisks and Afall into the gutter of the receiver and chute c' t', and therefrom are discharged at 2,- which is at the lowest point of the receiver and chute, as indicated by dotted lines in Fig. 3. By setting the receiver inclined the seeds will flow away continuously, but they may be raked out of the gutter by a hand implement. The seeds are delivered from the delinter-section A upon the tail-board cinto the eyeof the finisher or polisher, as will be seen from the IOO drawings. It is contemplated to have the iinished or polished seed fall through a blast, which will blow away the dust and fine lint wlthout carrying the seed along with the same, or the perforations r of the frictional cleaning and scouring disk K may be in communication with an air-trunk of a fan, which is connected with the delinting-section A, as in my aforesaid application, and this fine dust and lint may be carried into the same trunk.

In Fig. 9 of the drawings it will be seen that the blast-fan H is driven by a belt l, the agitator 'n2 by a belt 2, the endless feeder or elevator F by a belt 3, the endless slatted scourlng apron or belt a by a crossed belt 4, the shaft .I of the finishing or polishing disk L by a crossed belt 5, straight belt 6, and a pulley-shaft 7, all of said belts being driven from one shaft 8, provided with suitable-sized speed-pulleys. If desired, the belt 2 may be dispensed with and a different style of agitator substituted for the agitator n2, and of course the arrangement of the drivin g-gearing may be changed to suit location and movements of the machine, and instead of using only one section A of scouring mechanism two or more maybe employed, as in my aforesaid application.
